RAILROAD-SWITCH.

$PECIPICATION forming part of Letters Patent No. 349,250, datedSeptember 14, 1886.

Application filed January 12, 1386. Renewed August 23, 1886. Serial No.211,647.

To all whom it may concern:

Be it known that I, CHARLES M. ORosBY, of Hillsborough, in the-county ofHighland and State of Ohio, have invented certain new and usefulImprovements in Railroad-Switches; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of thisspecification, in which- Figure 1is a plan view of a section of railroad-track having my improved switchapplied, showing the main track open. 2 is a similar View of a portionof the track, showing the siding open. Fig. 3 is a det-ailsectional viewof the switch-block.

The invention relates to improvements in that class of railway-switchesin which a sliding frog forms part; and its object is to provide such aswitch of simple construction, of efficient action, in which the mainline and siding may be both closed, and in which, when so closed, thewheels ofacar passing from the siding to the main line will not have toride over the frog.

Theinvention consists in the construction and novel arrangement of partshereinafter described, and pointed out in the app ended claims.

Referring to the accompanying drawings, A A represent, respectively, theinner and outer rails of the main line, and B B the inner and outerrails of the siding. Where the lines of rails A B cross each other therails are cut away, so as to make a space, 0, of suitable length. ofsaid space toward the switch-lever are not in contact, but have betweenthem the space 0, wide cnoughfor the flange of a wheel to pass, asshown.

D is a bed-plate arranged to slide transversely with relation to themain track in ways secured to the tics or in recesses formed therein.

The bed-plate is just wide enough to fit in and slide easily through thespace 0 in the rails A B.

e is a switch-rod, which connects the bed plate with one arm of thecrank-lever E. The other arm of said lever is connected with a similarcrank-arm, E, by the rod 6 and the switch-rod e connects the other armof E with the switch-rails and switchstand.

The ends of the rails A B 011 the side (No model.)

of the rail A.

Between the grooves which run into each other at their ends f on theside 011 which the main track and side track approximate, the upstandingportion H of the bed plate is necessarily Vshaped, one side beingparallel with the main line and one with the siding. The point h of saidportion lies toward the side on which the tracks approximate, and thebase h on the other side is just wide enough to have one side coincidingwith the inner side of the rail A and have one side coinciding with theinner side of the rail B when the bed-plate is in the position showninFig. 1. WVhen the bed-plate is slid in, as shown in Fig. 1, the part Gwill coincide with the rail A, setting the frog to the main track andclosing the siding, so that a train cannot pass therefrom. When thebed-plate is slid into the position shown in Fig. 2, the part G isinward from the rail A and the part H lies in the space O, so that bothlines are open and a train can pass either Way on the main track andfrom the siding onto the same. If desired, the grooves might bedispensed with and the parts G and H might rise directly from thebed-plate; but the grooves are preferable, as they act as guardrails tothe flanges at the break in the line.

Any other form of switch-lever or device to move thebed-plate may beused.

K K are guardrails respectively upon the main track and siding, toprevent derailment at the point C.

It is evident that the invention can be used either with the class ofsplit switches or with the class of stub-switches.

The rod 6 is connected to the rails A B near 95 their ends adjacent tothe switch-lever, the ends of the said rails near the siding bed-platebeing secured to several ties, so that as the switchlever and rods 6 eare moved the rails A B close the main track and open the siding or theloo reverse simultaneously with the opening and closing of said tracksby the sliding bed-plate.

I am aware that switches have been made with a sliding frog forming partthereof, and such I do not claim, broadly; but,

Having described my invention, I claim 1. In a railway-switch, thecombination of the inner lines of rails of the main track and siding cutaway at their point of intersection, so as to form a space of desirablelength, a bed-plate arranged to slide within said space, and providedwith a straight transverse projection corresponding to a section ofrail, and a triangular transverse projection having one side parallel tothe siding, and mechanism, substantially as specified, to actuate thesaid bed-plate.

2. The combination of the main track, the siding, the movable rails A B,the bed-plate arranged to slide in the space 0, and provided with theprojections G and H, and switch mechanism, substantially as described,whereby the rails A B are simultaneously moved with the bed-plate, so asto open or close either the main track or siding, substantially asspecified.

3. The combination of the main track, composed of the rails A A, thesiding, composed z 5
